  2. 2. Ordnance Survey - key facts There is much more to Ordnance Survey than you might think...  Market leader with more than 200 years of mapping expertise  Data underpins around 10% of Great Britain's economic activity  Financed through data licensing rather than direct funding from taxpayers  More than 50% trading revenue comes from non-public sector customers  At the forefront of the drive to provide intelligent geographical information 2

  8. 8. Database centric cartography - Ed’s golden rule 1 “Separate representation Ordnance Survey Land-Line from data” Ordnance Survey MasterMap 9
  9. 9. Database centric cartography • Geometry is just an attribute ! • Multiple geometry's associated with a single feature • Multiple cartographic representations associated with each feature Feature Geometry’s Representations 10
  10. 10. Database centric cartography Digital Digital Real World Landscape Cartographic Models Models 11
  11. 11. Rebuilding the Factory 12
  12. 12. Project “Phoenix” • Multi-Million Euro investment programme to allow seamless object editing of core Digital Landscape Model • Supports Long Transactions • Basic service orientated architecture 13

  15. 15. Generalisation • Modifying the relative location and geometry of features • A difficult problem to automate • Current ‘best” solutions rely on AI systems e.g. LaserScan Clarity 16
  16. 16. Conclusions • Database centric cartography requires an shift in organisaition thinking • Huge benefits from deriving products from a “single source of truth” • New ESRI cartographic representation tools are a massive step forward • Generalisation is still a difficult problem • Operational solutions must support interoperability between systems 17
